INR21700-M50T — specification and pack integration
A 5,000 mAh 21700 built for energy, not current: the 7.275 A continuous ceiling is 1.5 C, and the figure is derated below 5 °C. NMC 811 cathode with a graphite-SiOx anode.
What the numbers mean for a pack
- 5,000 mAh typical in a 21700 can, at 3.63 V nominal
- 7.275 A discharge ceiling — the pack design must hold the cell inside its temperature cut-off to use it
- ≈267 Wh/kg
- DC ≈30 mΩ — the figure that decides voltage sag under load
Where it is used
- Residential and commercial storage modules charging and discharging at low C-rates
- E-bike packs with conservative controller limits
- Long-runtime portable equipment
Integration notes
Charge CC-CV to 4.2 V within the current limits above and stop discharge at 2.5 V. These are unprotected industrial cells: a BMS or protection circuit is required, interconnects must be resistance or laser welded rather than soldered, and cells of different model, batch or state of charge must not be mixed in one pack. Charging below 0 °C is not permitted unless the pack implements a low-temperature charge strategy.
Documentation
UN38.3 test summary, MSDS and the cell specification are available on request. Values shown here are pending verification against the manufacturer data sheet.
Specification basis: Publicly circulated LG specification — values pending verification against manufacturer datasheet
